Acid production from sugars and sugar alcohols by probiotic lactobacilli and bifidobacteria in vitro.
Some probiotic bacterial strains have been suggested to improve oral health. However, lactobacilli and bifidobacteria are associated with the progression of dental caries. The pH fall caused by 14 probiotic and dairy bacterial strains from glucose, lactose, sucrose, sorbitol and xylitol was followed. All strains used glucose, nine lactose and seven sucrose. Six of the lactobacilli caused a small decrease in pH with sorbitol and two with xylitol. None of the bifidobacteria fermented sugar alcohols. As all the strains could be considered acidogenic, more long-term clinical trials are needed before recommendations for oral health purposes can be made.
